无法访问泊坞窗映像中的React应用程序

我已经实现了一个React应用程序，并做成了docker。当我运行以下命令时，我无法访问react应用程序。命令：-docker run -p 3000：3000 reactapp

> [email protected] start /usr/src/app
> react-scripts start

我收到上述消息，但无法访问react应用程序。

以下是我的docker文件。

FROM node

# A directory within the virtualized Docker environment
# Becomes more relevant when using Docker Compose later
WORKDIR /usr/src/app

# Copies package.json and package-lock.json to Docker environment
COPY package*.json ./

# Installs all node packages
RUN npm install

# Copies everything over to Docker environment
COPY . .

# Uses port which is used by the actual application
EXPOSE 3000

# Finally runs the application
CMD [ "npm", "start" ]
